I'm looking for an inexpensive, high resolution, audio-domain A to D
converter for a Mac II.  Ideally, it will have 2 channels, 16 bits, >44KHz
sampling rate, SCSI or NuBuss interface, programmable gain, high linerarity,
and cost <$500.  One channel would really do the trick, and I could
live with 14 bits if it were substantially cheaper.  Other interfaces
would also be OK.  Below are the systems I know about.  Does anybody
out there know of any other options?   Suggestions might include:
plans, chip sets, kits, used equipment sources, etc.  Thanks for 
any help you can offer.
